Application fi e November 14, 1894:. Serial No. 523,768- (No model.)

Io all whom it may concern.-

Be it known that 1, WILLIAM STRAIT, a citizen of the United States,residing at Elmira, in the county of Ohemung and State of New York, haveinvented certain new and useful Improvements in SideHill Plows, (Case13;) and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention relates to plows.

The object of my invention is to provide a sidehill plow and itsreversible moldboard with novel means for shifting the colter andjointer.

Figure 1 represents a side elevation,partly broken away, of a plowembodying my invention. Fig. 2 is a sectional view on the Fig. 3 is asectional view on the line y 'y of Fig. 1. Fig. 4 is a detail view ofthefront edge of the standard. Fig.

5 is a detail side elevation of the standard and handles, showing thecolter removed from its position in Fig. l and a jointer substitutedtherefor. Fig. 6 is a perspective view of the jointer and its operatingmechanism.

The standard A is provided with an inclined fore and aft hole or openingB within which eitherthe colter O or the jointer D may operatively rest.When the colter O is used with this sidehill plow, the relation of theparts is as shown in Figs. 1, 2 and 3.

The opening B in the front of thestandard is vertically elongated, andthe shank E of the colter is of similar dimensions as said opening atthat point. The opening B flares laterally from the front toward therear edge of the standard so as to provide a lateral 0s cillating motionto the colter-shank.

F are the shifting handles of the plow pivoted at any suitable point,and carrying-a plate G bolted on the under side thereof, and providedwith lugs H which act, through the intervention of the lever I tooscillate and shift the colter 0 whenever the handles and the moldboardare shifted.

The lever I oscillates upon a pivot J carried in the standard and itsupper end is recessed providing an openingK through which the rear endof the colter shank E projects. A curved bolt M is secured to theleverIand traverses this opening K passing through an eye in the rearend of the shank E. The lower end of lever I constitutes a projectionwhich lies between the lugs H on the handles.

The opening K is of such lateral dimensions that the lever Ioscillatesto some extent before that actuating side wall of the open- (dependingin what direction the colter or jointer is tobe-shifted) comes incontact with the shank of the same for shifting it. The initial part ofthis motion in either direction is lost motion, the end movement of theoscillation accomplishing the shifting of the shank of the colter orjointer, such shank projecting through said opening.

In operation, when the moldboard and handles are shifted by being thrownto the right, for example, the lugs H are thrown to the left, moving thelower end of lever I in that direction, and the upper end thereof in theopposite direction, or to the right. The opening K, also moving to theright, its rear edge comes in contact with the colter shank E shiftingit laterally to the right until it bears against the side wall of theopening B where it is securely held. The colter 0, being at thecpposite' end of the shaft is carried to the left for its operativeposition when the moldboard is thrown to the right, the colter and sharebeing in alignment. It will be seen that a precisely reverse operationtakes place when the moldboard and handles are shifted to the left. Thebolt M passing through the eye of the shank holds the colterin operativeposition and at the same time allows a. free operative movement to theshank.

O is a lug formed on the rear of the standard which overlaps the upperedge of the lever I and aids in holding that lever in place during itsmovements.

When it is desired to substitute the jointer D for the colter G thelatter is removed and the rotaryshank P of the jointer inserted in theopening B, said opening having circular portionsR therein within whichthe shank P has its bearings. The lever I is then removed, and the levercollar S is substituted and secured to the rear end of the shaft P, thecollar S being received within the lug O on the standard. The casting Tis then bolted on the upper end of the handles and has a pin whichengages with the collar lever S for shifting the jointer when themoldlooard and handles are shifted.

I claim- 1. A colter or jointer shifting lever provided with anintermediate pivot having a projecting arm on its lower end and anopening in its upper end, within which the colter or jointer is shifted.

2. A colter or jointer shifting lever having a projecting arm on itslower end, an opening in its upper end provided with a bolt for bold-WM. STRAII. Witnesses:
